WASHINGTON (Reuters) - Top U.S. Capitol security officials apologised on Tuesday for "failings" during the deadly attack on the building by followers of then-President Donald Trump in a bid to stop the certification of Joe Biden's election victory.

The officials specifically acknowledged a number of missteps: conflicting intelligence, inadequate preparation and insufficient mobilization of partner agencies, and called for improving accountability systems and communications structures.
